The James Taylor Quartet are a British four-piece jazz funk band, who have become renowned for their live performances. They were formed in 1987 by Hammond organ player James Taylor following the break-up of his former band The Prisoners in the wake of Stiff Records' bankruptcy. The current line-up is James Taylor (Hammond organ), Chris Montague (guitar), Andrew McKinney (bass) and Adam Betts (drums), although recordings and live performances usually feature a horn section comprising John Willmott (tenor sax/flute) and Nick Smart (trumpet), and also vocalist Yvonne Yanney.

The band is often referred to by the acronym JTQ, and have no connection to the American singer-songwriter James Taylor.
